TOBAGO-1870 The file attribute of tc:style is not rendered after a submit.

This box will be diplayed with background color #ffddff, because of the CSS class ".demo-selected". The color is defined in the local file "style/demo.css".

The bug: After a click of "reload" the style is broken, because the include of the demo.css is missing.

The problem only occures with `<ui:include src="x-event-\#{''}.xhtml"/>`.

The problem NOT occures with `<ui:include src="x-event-.xhtml"/>`, but the EL should resolve to excactly the same string.

Here is included an empty facelet...
